Quadro K620 vs GeForce GTX 860M benchmarks

In our benchmarks, the GeForce GTX 860M beats the Quadro K620 in gaming performance.

Our database shows that the GeForce GTX 860M has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. Despite this, the Quadro K620 has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Quadro K620 has a significantly lower TDP at 45 W when compared to the GeForce GTX 860M at 75 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 860M over the Quadro K620.
